Capacitors in Parallel - calculations electronics engineering

The video tutorial explains how capacitors can power a lamp when placed in parallel, especially when a battery is removed. It covers the calculation of total capacitance by summing individual capacitors' values and discusses practical applications such as noise filtering and providing more current in high-demand circuits. The tutorial also details how to calculate the total charge stored in parallel circuits using the formula charge equals total capacitance multiplied by voltage.

What happens to the lamp when the battery is removed and a capacitor is used?

• The lamp turns off immediately.

• The lamp stays on indefinitely.

• The lamp slowly dims as the capacitor discharges.

• The lamp becomes brighter.

How do you calculate the total capacitance of capacitors in parallel?

• Multiply the capacitance values.

• Divide the capacitance values.

• Add the capacitance values.

• Subtract the capacitance values.

If you need a 2000 microfarad capacitor but only have smaller ones, what can you do?

• Combine smaller capacitors in series.

• Use a single smaller capacitor.

• Combine smaller capacitors in parallel.

• Use a resistor instead.

What is the formula to calculate the total charge stored in parallel circuits?

• Charge = Voltage / Total Capacitance

• Charge = Voltage - Total Capacitance

• Charge = Total Capacitance x Voltage

• Charge = Total Capacitance / Voltage

How much charge is stored when the total capacitance is 330 microfarads and the voltage is 9 volts?

• 0.00330 Coulombs

• 0.00165 Coulombs

• 0.00297 Coulombs

• 0.00207 Coulombs
